1 Claim lCl. 259-131) Ourpresent invention. relates to improvements inegg beaters of the rotary, hand operated, crank and gear type employinga pair of separable beaters which may readily be removed and re- 1 5placed, in order that the several parts of the device or implement maybe thoroughly washed and dried when required, to maintain the implementin clean, sanitary condition.

As is well known to those familiar with the ,0; culinary art, difficultyis encountered and much time is ineffectually employed in the attempt tosuccessfully wash and dry the non-separable type of egg-beaters, and inthe separable type of egg beaters, it is desirable and necessary thatthe 5 devices shall not only be securely retained against displacementof the beaters while they are in operating position, but theconstruction and arrangement must also be simple, and not intricate, inorder that the housewife, or the helper, may,

2Q without difficulty and without undue labor, displace the separablebeaters for cleaning. Another requisite for the desirable and efiicientimplement is the ability to restore the beaters to operative positionwithout the necessity for ex- 5: pert labor, and without necessity forresorting to unusual force in assembling the separated parts of theimplement.

In carrying out our invention we provide an implement which iscomparatively simple in construction and operation, which may bemanufactured at a low cost of production, and from which the beatersmay, with convenience and dispatch, be readily separated, and with equalfacility these separated beaters may again be 3 assembled in positionfor use.

Our invention consists in certain novel combinations and arrangements ofparts in the separable beater as will hereinafter be more fully setforth and claimed. In the accompanying 0 drawing we have illustrated theinvention in the best modes we have so far devised for the practicalapplication of the principles of our invention.

Figure 1 is a view in elevation of an egg-beater i-embodying ourinvention, showing by dotted lines the mode employed for removing orreplacing one of the beaters, and Figure 2 is a view in elevation of thebeater, as seen from the right in Figure 1.

Figure 3 is an enlarged detail view, partly in section, showing thelower journal bearings for the heaters, and Figure 4 is a detail view,partly in section, showing journal bearings at the upper ends of thebeaters.

In the preferred form of the invention, as illustrated in the drawing,we'employ a main frame 1 having a rigid handle 2 which is grasped, as inthe left hand, for holding the beater in operative position, and a maingear wheel 3 is journaled at 4 in the main frame. The main gear wheel isfashioned in the form of a sheet metal disk, and at opposite sidesthereof the metal is struck from the body of the disk to form theannular series of teeth 5, thereby providing an annular series of teethnear the outer periphery of, and at each side of the circular disk orwheel. The wheel is revolved in its bearings through the use of a crank6 which is provided with a handle or loose knob '7, and the latter isgrasped, as in the right hand, and turned for operating the beater.

The main frame, at its lower end, is provided with a head portion 8, andthe beater frame 9 is rigidly attached to this head. Preferably thebeater frame is fashioned as a bowed, or U- shaped body, of resilientmetal, and as indicatedby dotted lines in Figure 2, this frame may becompressed as to its width and thereby extended in length to facilitatethe separation from the implement of the two beaters indicated by thenumerals 10 and 11. The beaters are of usual type and circular in form,and each beater is provided with a spindle 12 at the upper end of whicha reduced extension 13 forms a journal pin, and the pinion 14 for eachbeater is fitted over this pin and seated on the shoulder or abutment14'. The pinions are thus securely mounted on the heaters and they arelocated one at each side of the gear wheel for co-action therewith inrotating the beaters.

Each beater, at its lower end, is also provided with a lower journalpin, axially alined with its upper journal pin 13, and these lower pinsare designated by the number 15.

At the lower end of the beater frame a cross head 16 is rigidly mountedon this frame and at the opposite ends of the cross head bearing holes1'7 are provided for the reception of the journal pins 15. As bestindicated in Figure 3 the upper face of the cross head is fashioned withalined grooves 18 that extend outwardly from the holes 17 and terminatewith rounded or downwardly turned ends at the respective ends of thecross head. Thus, as indicated in Figure 3, the cross head is ofresilient metal and the opposite ends of the cross head may be depressedto permit dislodging of the pins 15, and the pins then slip along thegrooves 18 as the beater is being separated from the implement. Inassembling the beater in place, the pin is slipped along the groove,(and the end of the resilient cross head is bent down if necessary)until the pin is snapped into the hole 17, the groove thus acting as aguide for the pin as the beater is removed or replaced.

In Figure 1 the frame 9 may be compressed as to its width, as indicatedby dotted lines, to extend the length of the frame, and the hole 17 isthus disengaged from the journal pin, after which the pin is slippedoutwardly, through the guide groove. The compression laterally, andextension longitudinally of the beater frame, and the resiliency of thecross head 16 both contribute to ease and convenience in removing andreplacing the beaters.

The upper ends of the heaters are also readily detached and attachedwith a snapping action by the use of resilient bearing arms 19 on thehead of the main frame, and these arms are provided with hearing orjournal holes 20 for the upper journal pins 13 of the heaters.

Thus, it will be apparent that, with the left hand grasping the handle2, the right hand may be used to grasp a beater, and the upper and lowerpins of the beater'are disconnected from their bearings with only aslight exertion, to separate the heaters from the implement, and withequal facility, these heaters may be replaced.

Having thus fully described our invention, what we claim as new anddesire to secure by Letters Patent is:

In an egg beater, the combination with a main frame and a heater framerigid therewith, said heater frame comprising a U-shaped yoke ofresilient material adapted to be compressed laterally for causinglongitudinal extension thereof, oppositely extending resilient armshaving bearing holes and rigid with the main frame, a cross head ofresilient material having its central portion rigid with the free end ofthe yoke and spaced bearing holes in said head, and said cross headhaving in its upper face guide grooves leading from its free ends tosaid holes, of a pair of separable heaters each having axially alinedjournal pins supported in alined holes of the arms and head, and meansfor operating the heaters.
